To all whom it may concem:

Be it known that I, Ronnn'r B, SMITH, a citizen of the United States, residing at Stoughton, in the count of Norfolk and State of Massachusetts, ave invented certain Improvements in Eyeleting Machines, of which the following description, in con nection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to improvements in machines for setting fasteners and particularly to machines for setting blindand invisible eyelets in manufacturing boots and shoes.

By the use of the novel setting device of this invention it is practicable to insert fasteners such as blind or invisible eyelets in shoe uppers after the upper leather and linin parts of the upper have been stitched together along the lacing slit and around the top of the upper, without disturbing the normal relation of those parts of the shoe upper. This is particularly advantageous,

as compared with the prior practice of parting the leather and t e lining parts after the lacing holes had been punched, so that the eyelets would be set in one or the other of those parts after the fashion of regular visible eyelets, leaving the uneyeletted lacin holes in the other part, in that it pro vides for performing in a single operation what previously required two separate operations and in that it produces work of a very superior quality,

The novel fastening inserting machine of my invention may be used with advantage in carrying out a method of manufacture consisting in permanently securing together, as by stitching, the leather and lining parts of an upper in that relation which they are to have in the finished shoe, then punching a hole through both parts by the use of a combined punching and setting device, feeding the work without withdrawing the device, and finally inserting an eyelet through No. 76,639 filed February 7 1916, of which the present application is a division.

As herein shown the upper is supported upon a yleldingly mounted cutting block and 1n a feeding operation the combined punching and setting tool is moved transversely over the surface of the yielding cutting block. This construction prevents the possibility of the work slipping off the end of the punching and setting device during the feeding operation and so contributes to the accurac and efficiency of the machine.

These an other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings, in which,--

Fig. 1 1s a view in perspective of portions of an eyeleting machine of well known construction having my invention embodied therein;

Figs. 2, 3 and 4 illustrate successive steps 1n the punching, feeding and setting operations; and

Fig. 5 is a view inperspective of a portion of a shoe upper, artly broken away, to show the clenched end of an invisible eyelet.

The machine illustrated in Fig. 1 will readily be identified as the well-known Sam-- son eyeleting machine shown, for example, in United States Letters Patent No. 1,205,- 277 granted Nov. 21, 1916, on an application of Walter Shaw. Such ortions of the machine as are not herein ilustrated may correspond to similar parts of the machine illustrated in said Letters Patent. The machine frame 2 has mounted thereon a lever 4 which is arranged to be moved vertically to efiect the punchin operation and also transversely to effect t e feeding operation. The tool 20 mounted in this lever has the combined functions of punching and feeding the work as well as upsetting or clenching the end of the eyelet barrel. As shown in Figs. 2 and 3 the tool is of tubular construction having an opening extendlng completely through it to afford passage for the punchings. ts lower edge 1s shaped to perforate the work in combination with a cuttin block 22. A short distance above its en the tool is provided with an outwardly and upwardly curved shoulder 19 which constitutes the upsetting surface. This upsetting surface does not extend sufiiciently to engage the prongs of the eyelet barrel during the entire clenching operatlon and in this sense may be termed an incomplete or restricted upsetting surface :or shoulder. Its reduced diameter is, of course, for the purpose of facilitating its introduction through a layer of the work perforated by the tool.

The frame 2 carries a stationary work table 6 perforated for the passage of the setting tools and slotted to receive the punching block, 22. The punch block is shown in detail in Fig. 2. It is provided with a downwardly extended shank and is mounted for a limited vertical movement in ways formed in a stationary block 8. -The block 8 has sockets for a pair of springs 12 which bear beneath the opposite ends of the block 22 and tend normally to lift it. The normal position of the cutting block is adjustably controlled by a stop screw 14 set in av lug in the lower end of the shank 10 and bearing against the under surface of the stationary block 8. An anti-friction roller 16 is journalled in the block 8 in position to bear upon one side of theshank 10 and thus prevent cramping of the shank and consequent loss of free vertical movement in the cutting block which might result from the pressure of the punch upon the end of the cutting block where the punch would ordinarily act.

The frame 2 is provided with vertical bearings for a plunger 18 in the upper end of which is mounted the lower or eyelet inserting die 17 The inserting die 17 1s provided with a center spindle 15 which is adapted to pick one eyelet after another from the end of a raceway 13 preliminarily to each inserting operation. A vertically movable presser foot 11 is provided for holding the work at rest upon the work plate 6 between the feeding operations.

'In using the mechanism herein illustrated for setting invisible eyelets the stitched upper ispresented upon the work table 6 with the point at which the first eyelet is to be set above the cutting block 22 and in alinement with the tool 20. The machine is thereupon started and the tool is moved downwardly, perforating both parts of the u per and slightl depressing. thecutting bibck as shown in l ig. 3. The tool 20 is then lifted sufiiciently to permit the cutting block to return to its normal position andis then moved transversely toward the left, as

shown in Fig. 4, with its end in light engagement with the surface of the cutting block. It will be seen that when the feeding operation is carried out in this manner there is no possibility of the upper slipping ofi' the end of the feeding tool. The feedingoperation terminates with the tool 20 in alinement with and above the inserting die 17 to which an eyelet has been supplied by the raceway. In the final step of the cycle the inserting die is elevated and the end of the eyelet barrel forced through the lining part of the upper, being guided by the reduced end portion or pilot of the tool 20 against the upsetting shoulder 19.

The position of the tools at the conclusion of the setting operation is shown in Fig. 4.

Having now described my, invention together with one method in which it may be used, I claim as new and desire to secure by Letters Patent'of the United States:

1. An eyeleting machine having, in combination, a combined punching and setting tool having an upsetting shoulder shaped to be projected through one of several layers of a shoe upper perforated by the tool, and means for inserting an eyelet through the other layer or layers and clenching it against said shoulder.

2. An eyeleting machine having, in combination, a yieldingly mounted cutting block, a combined punching and setting tool having an upsetting shoulder shaped to be projected through one of several layers of a shoe upper supported on said block, and movable transversely of the block to feed the upper, and an eyelet inserting set.

3. In an eyeleting machine, a combined punching and setting tool having a tubular end shaped for punching, and an upsetting shoulder of such small diameter as to facilitate its introduction in the hole formed by the end of the tool and being shaped to form an incomplete upsetting surface.

4. An eyeleting machine having, in combination, a punch, a cutting block extending at one end into line with the punch, springs for supporting the block located adjacent -to opposite ends thereof, a shank projecting serted into concealed clenching position between the parts of an upper without disturbing the normal relation of the parts, the

body portion of the tool being shaped to support the shoulder in its concealed position.

and arranged to follow the pilot portion through one or more of a plurality of layers of material to clench a fastener between ad- 10 jacent layers of the material.
